Why is Priyanka Gandhi Vadra, who is known to be the sure consultant of brother Rahul in his every political decision, out of the arena for a while? Family sources say that she is busy penning a tome on father late Rajiv Gandhi, gathering all her memories. Sources reveal that many a publisher had queued up to take up this sure-fire book, but Priyanka has decided to give it to Penguin India. It is learnt that the book will hit the market just ahead of the 2019 polls, to be released by mother Sonia Gandhi. The release could take place this December or early next year. Gandhi family well-wishers believe that the emotional content of the book is likely to have some impact on the 2019 polls.
